STMicroelectronics has added the TSV782 high-performance dual op-amp to its 5V family, with 30MHz gain bandwidth (GBW) and 50µV (typical) input offset voltage for high-speed, high-accuracy signal conditioning. This new device can operate from a deeply discharged battery and so extend the runtime of equipment such as smoke alarms. It is able to function with a supply as low as 2.0V and the operating current of just 3.3mA/channel helps designers maximize the application energy budget to power richer functions and capabilities such as innovative smart features and wireless connectivity.


The TSV782 op-amp has a maximum input bias current of 300pA up to 125°C, enabling accurate signal conditioning with high-impedance sensors or in trans-impedance configuration. The high accuracy of ST’s 5V op-amp family lets designers create circuits that require no trimming or calibration during production, saving expensive external components such as precision resistors and potentiometers. Moreover, operating down to 2.0V also lets the op-amp use the same power rail as low-voltage logic devices to simplify system design and lower the bill of materials.
